Ductless Mini-Split Systems in Jacksonville & Ponte Vedra

Not every space in your home is served by ductwork, and not every comfort problem requires a whole-house solution. Ductless mini-split systems deliver targeted heating and cooling to specific rooms or zones without tearing into walls or ceilings to install ducts.

PV Plumbing & Air installs, repairs, and maintains ductless mini-split systems across Northeast Florida. Whether you’re adding comfort to a bonus room, converting a garage, or solving a hot spot that your central system can’t reach, mini-splits offer a precise, efficient answer. Contact us today.

Where Mini-Splits Make Sense

Home Additions & Room Conversions

Added a bedroom, finished a bonus room above the garage, or enclosed a patio? Extending your existing ductwork to reach these spaces is often expensive and impractical. A mini-split gives the new space independent climate control without taxing your central system.

Garages & Workshops

Florida garages get brutally hot. A mini-split turns your garage into a usable workspace year-round, without the cost of running ductwork from your main system.

Sunrooms & Florida Rooms

These glass-heavy spaces absorb tremendous solar heat. Your central AC often can’t keep up, and the thermostat in the main house doesn’t know the sunroom is 15 degrees warmer. A dedicated mini-split solves this.

Older Homes Without Ductwork

Some older Northeast Florida homes were built without central ducts, relying on window units or space heaters. Mini-splits provide modern, efficient whole-home comfort without the major renovation of installing a duct system.

Hot and Cold Spots

If one room in your house is always warmer (or cooler) than the rest, a mini-split can supplement your central system and eliminate the temperature gap, without over-cooling the rest of the house.

Home Offices

Working from home in a room your central AC can’t quite keep comfortable? A mini-split gives you precise temperature control for your workspace without adjusting the whole house.

How Ductless Mini-Splits Work

A mini-split system has two main components:

Outdoor compressor/condenser unit, Sits outside your home, similar to a central AC outdoor unit but smaller. One outdoor unit can power 1–5 indoor units depending on the model.

Indoor air handler(s), Wall-mounted, ceiling-mounted, or floor-mounted units inside the room(s) you want to condition. Each indoor unit has its own thermostat and remote control.

The two are connected by a small refrigerant line and electrical cable that runs through a 3-inch hole in the wall, no ductwork, no major construction.

Key Advantages

• Zone control, Each indoor unit operates independently. Cool the living room to 72°F while the guest room stays at 76°F.
• No ductwork energy loss, Central AC systems lose 20–30% of cooling through duct leaks. Mini-splits eliminate that loss entirely.
• Quiet operation, Indoor units produce 19–40 decibels, quieter than a normal conversation.
• Heating and cooling, Every mini-split is a heat pump. It cools in summer and heats in winter from the same unit.

Mini-Split Configurations

Single-Zone Systems

One outdoor unit, one indoor unit. Perfect for a single room addition, garage, or problem area.

Typical cost installed: $3,000–$5,500 depending on capacity and brand.

Multi-Zone Systems

One outdoor unit powering 2–5 indoor units in different rooms. Each zone has independent temperature control.

Typical cost installed: $5,000–$12,000+ depending on the number of zones and capacity.

Ceiling Cassette Units

Mounted flush in the ceiling for a sleek, nearly invisible look. Distribute air in four directions for even coverage. Popular in modern renovations and commercial spaces.

Floor-Mounted Units

Sit low on the wall near the floor. Good for rooms with limited wall space or large windows. Effective for heating since warm air rises from the floor level.

Mini-Splits in Florida’s Climate

Northeast Florida’s heat and humidity make mini-splits especially effective:

• Inverter technology, Modern mini-splits use inverter compressors that run continuously at variable speeds rather than cycling on and off. This provides better humidity control, critical in Florida where 80%+ humidity is the norm.
• High SEER2 ratings, Mini-splits routinely achieve 18–30+ SEER2, making them among the most efficient cooling systems available. That translates to measurably lower electricity costs.
• Hurricane resilience, Indoor units are protected inside the home. Outdoor units are compact and can be installed in sheltered locations. In a power outage, mini-splits restart cleanly when power returns.

Our Installation Process

Site Evaluation

We assess the space, measure heating and cooling loads, and recommend the right unit size and placement for optimal airflow and performance. Talk to us about how to improve your indoor air quality as well, today.

Unit Selection

Based on the evaluation, we recommend systems from brands like Mitsubishi, Daikin, Fujitsu, LG, and others. We’ll match capacity, efficiency, and features to your space and budget.

Professional Installation

Installation typically takes 4–8 hours for a single-zone system. We mount the indoor unit, place the outdoor unit, run the refrigerant line, make electrical connections, charge the system, and test everything. The wall penetration is small (3 inches) and sealed to prevent air and moisture intrusion.

Commissioning

After installation, we verify cooling and heating performance, set up the remote control and any WiFi connectivity, and walk you through operation and filter maintenance.
